Power Line Filter Modules Procurement Notes

Verify the specific part number FMBC-R91S-5512 against official Schurter documentation to confirm the 55 A rating and two-stage configuration. Ensure compatibility with 520 VAC systems and check terminal torque specifications for M6 screws. Confirm operating temperature range requirements match your application environment before procurement.

Power Line Filter Modules Selection Notes

Select this component when a three-phase filter with a 55 A current rating and low leakage current is required. The two-stage design offers enhanced attenuation compared to single-stage alternatives. Verify that the chassis mounting style and M6 terminal interface align with your system's mechanical constraints and wiring standards.

Power Line Filter Modules Part Context

This component belongs to the Schurter FMBC NEO series, which provides compact and efficient EMC solutions.
